The Department of Education is administered by the United States Secretary of Education. It has under 4,000 employees (2018)[1] and an annual budget of $68 billion (2016).¹
More info at the Education Departments website.²
I don't think that's the right number though? That's just what the Education Department spends each year administering education? The FY 2019 Education Budget Fact Sheet² goes on to say:
"The Budget supports $129.8 billion in new postsecondary grants, loans, and work-study assistance to help an estimated 11.5 million students and their families pay for college
So there's clearly more funds being directed to education than just the $68B.

A quick googling says there's 50.7 million public school kids in the country, you're saying we only spend ~$1,300 per kid? Yeah, that's clearly wrong, you're either making that number up or are quoting the wrong number. And that's not even taking into account any university or adult education spending.
